摘要
差动保护是变压器运行中的关键保护,目前实际应用中大多数为微机型.重点讨论了几套不同装置的理论归算原理,并结合现场调试情况,介绍了一些装置的特点及调试时应注意的事项.
While the existing transformer protection used in real work is micro-computer-based protection. The theoretical connection alternation for different types of protection device from different suppliers in acfual spot testing are discussed. This paper mainly deals with the feautures of these devices and their key debugging process.
